To all whom it may concern:

Be it known that I, FREDERICK R. BESSANT, a citizen of the UnitedStates, residing at Atkinson, in the county of Henry and State ofIllinois, have invented certain new and useful Improvements in Disks forlDisk Plows; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to consists in forming the peripheral or cutting edge of thedisk with a series of scallops or recesses of a peculiar shape orconfiguration by which the forward or entering edge of the recessedportion will grasp the trash and draw it inwardly at a relatively sharpangle while the receding or rearwardly extending portion will graduallycut or sever the trash or corn stalks in the rotation of the disk. Thispeculiarformation of scallop or recess also insures the disk taking andholding a better grip on the heavy soil so as to tend to prevent thedisk from being lifted up or out of the soil in plowing.

To the accomplishment of the foregoing the invention consists in thefeatures hereinafter particularly described and then sought to beclearly defined by the claim, reference being had to the accompanyingdrawing forming a part hereof, and in which- Figure 1 is a side view ofa disk plow having disks embodying the invention;

Fig. 2 is a side view of one of the disks, lloolliing at the rear orconvex side of the Fig. 3 is a vertical section through a disk;

Fig. 4 is a side view of a disk looking at the front or concave face ofthe disk.

In the drawing the numeral 1 designates the plow frame, wheels, andoperating levers, all of a well known construction, and 2 designates anumber of disks, four being shown merely for purposes of illustration,and connected to arms 3 extending from the beam in any of the well knownways for permitting rotation of the disks. are each formed with a seriesof scallops or recesses 4 at regular distances apart and of any desirednumber in each disk. These scallops or recesses are of a speciallyformed shape or configuration as illustrated, the same having arelatively sharp curve or are at its forward or entering edge as at aand a curve of a relatively greater are from the shorter arc to the rearend of the recess, as at b, so as to present a gradually receding edgealong such portion. With the scallop or recess formed as described, theforward portion thereof in the rotation of the disk will grasp and drawinwardly and downwardly any trash, such as dead grass and corn stalks,which will be cut or severed by the sharp edge of the recess and thegradually receding feature of the longer are of the recess will preventthe trash from choking the disk and a tendency to lift the disk from thesoil. The relatively sharp curve at the entering edge of the recess alsotends to afford a better grip on heavy gumbo soil so that the disk willbe held to the soil instead of having a tendency to be lifted out of thesoil. The two characteristic features of the recess serve a usefulpurpose for the eflicient plowing of the soil, and the out ting of thetrash and preventing it from climbing the disk and accumulating aboutthe beam and thus interfering with the chicient working of the plow. Inactual plowing the advantages of the particular formation of therecesses in the disk have been demonstrated by satisfactory resultsattained.

The edge of the disk between the recesses as well as along the recessesis formed on a bevel as indicated at 5.

I have illustrated four disks applied to the plow but there may be agreater or less number, and the disks may be supported in any Well knownmanner so as to rotate.

The disks Having described my invention and set both curves describing aconeave line, subforth its merits, what I claim is stantially asdescribed. 10
